An efficient hybrid cooperation communication method which can be used in inclement channel conditions is proposed.For two users,the source node transmits the data using QPSK modulation over two frames.Based on HARQ,the source node redelivers data to the relay node when the transmitted information is not decoded correctly.The information is combined decoded together with the last transmitted information by the relay node.The relay node switches to amplification forwarding mode when the retransmitted data is still not be decoded correctly.Analysis and simulation results show that the proposed cooperation method outperforms the no cooperation method and the conventional coded cooperation method in inclement channel conditions.
